THOMAS B. O. BURPEE, OF PHILADELPHIA, PEl NS'IL'VANL -L COFFEE-ROASTER.

SPECIFICATION forming part of Letters Patent No. 311,955, dated February10,1885.

A pplicaiion filed January .24, 1884. (No model.)

To aZZ whom it may concern Be it known that I, THOMAS B. O. BURPEE, acitizen of the United States, residing at Philadelphia, Pennsylvania,have invented a new and useful Coffee-Roaster, of which the follow ingis a specification.

My invention relates to the hot-air casing which incloses thecoffee-cylinder. This casing is placed over a stove. It has a circularsliding door, similar to that over an office-desk, and its parts are soconstructed that by a movement of the sliding door the coffee-cylinderis completely inclosed and brought immediately over the fire-in thestove. \Vhen not in use for coffee-roasting, the sliding door is movedabout one or two inches, so as to form a direct draft-opening close tothe top plate of the stove, in which position the stove becomes a veryefiioient broiler, the steam and odor being carried up the aforesaidopening; also, by the addition of a tin reflector in front, the saidhot-air casing is turned into a bakeoven, thereby forming an extremelyuseful apparatus for hotels and large public institutions.

The construction of the machine is shown by the accompanyingillustrations, in which Figure 1 is an end elevation of the machine.Fig. 3 is a plan of the top plate of the stove. Fig. 4 is a verticalsection. Fig. 5 is a crosssection through the interior. Fig. 6 shows thegroove in the end plates in which works the circular sliding door. 7

A is the base-plate of the machine, B the fire-chamber, b the grate, andIf the ash-pit door. Upon this stove or range a hood, 0, is fixed,commencing at the top plate, F, and continuing on in a circular form toc, a little beyond the smokeoutlet E. About one or two inches distantwithin this hood is a circular sliding door, D, terminating at the topjust beyond the chimney at d and at the bottom at (F. A fixed piece ofcircular casting, (1 continues from its lowest edge, (1 to the topplate, F, of the stove. Thus there is formed a closed smokeflue, G,between the hood and the sliding door from the firechamber 13 to thechimney E. A narrow strip the width of the flue closes it at K,defleeting the smoke up the chimney. This circular sliding door Dextends, as also does the hood and stove, the entire length of the machine, and each end of the door D slides in a groove formed between tworibs, h, 41 shown in Fig. 6,) cast upon the end plates, H. handle or lipis cast on the door at (P, by which it is lowered or raised.

In each end plate, H, is formed a slot or groove, L, for guiding andsupporting the journals or of the coffee-cylinder while in position orwhen removing it. A slight depression, at a", at each end of the groovedetains the receptacle either within the hood or in position foremptying, which latter is shown by the dotted lines M.

Upon the journals of the cofiee-cy-"linder, at each end, are fittedlinks m, connected to links on", the latter secured upon a shaft, in,pass ing at the back of the machine. A handle,

N, is also upon this shaft, by the turning of which the coffee'cylinderis drawn into or removed from the hood. These slots L are coveredoutside by a door, 1, hinged at p. The door is heavier at its outer end,so that by gravity it remains over and covers the slot, unless forcedoutward by the motion of the handle N'when emptying the coffee-cylinder.

F is the top plate of the stove, (see Fig. 3,) to which are fitted theremovable plates f f f".

It is a tin reflector with a hook at its top side, by which it issuspended from the edge 0 of the hood. When in this position, it coversthe opening in the hood from c to 0', so as to form a baking-oven overthe top plate of the stove. At the back of the stove I provide for aclothes-drying apparatus. A strut, S, has a toe at its lower end fittinginto the baseplate. It is held in position by the link m, or a similarone. There is one of these struts at each end. Notches are out in thesestruts, in which are laid rods S, upon which rods the clothing is hungto dry.

The machine is used as follows: The top plate, F, is removed from thefire. The coffee cylinder is placed in its bearings n and filled withcoffee. The links on are placed on its journals, ,and by a motion of thecrank N the cylinder is drawn withinthe hood and rests in the centerbearings, a The door P follows the journal by gravity and closes theslot L.

A small x IOO The sliding door D is now drawn to cover the front openingcompletely and make a closed chamber, through which the hot gases whichwere previously passing up the flue G now pass direct to the chimney E.When the coffee is roasted, it is removed in a similar manner. The topplate, F, is replaced with one or more of the plates f f f, and thestove can be used for broiling. (See Fig. 5.) The door D is pushed innearly to its original position, leaving a longitudinal aperture intothe flue the entire length of the stove, and one or two inches widebetween d and d. The sharp current into this opening carries off thesteam and odor from the broiling meat. The machine can now be used asanoven The door D is placed with its lower point at d to close the steamand odor inlet. The lids f f f are placed onthe plate F, shelves areplaced upon the end ledges, h the reflector R is placed over the openingfrom c to 0 and a bakingoven is thereby formed over the stove-plate.

Irclaim- V 1. In a cofl'ee-roastingmaehine, the combination of a stove,a hood, 0, an inside sliding door or hood, D, and a flue, G, formedbetween them, as herein described.

2. The combination of a stove with an exterior hood, 0, directly overthe fire, an interior sliding door, i5), and a removable door, R, asdescribed.

3. In a coffee-roaster, the combination of the slotted end plates, H,which serve as guides and supports for the journals n of thecoffeecylinder, and the shaft m connected to the journals of by thelinks m m operating in unison as described.
